TECHNICAL FIELD

The present invention relates to improved cosmetic cleansing compositions, and in particular to foaming cosmetic compositions suitable for cleansing the skin and/or the hair and which may be used, for example, in the form of make-up removal and facial cleansers, bath foams, shower products, shampoos and the like.

BACKGROUND OF THE INVENTION

Foaming cosmetic compositions must satisfy a number of criteria including cleansing power, foaming properties and mildness/low irritancy with respect to the skin, hair and the occular mucosae.

Skin is made up of several layers of cells which coat and protect the keratin and collagen fibrous proteins that form the skeleton of its structure. The outermost of these layers, referred to as the stratum corneum, is known to be composed of 250 A diameter protein bundles surrounded by 80 A thick bilayers of epidermal lipids and water. Anionic surfactants can penetrate the stratum corneum membrane and, by delipidization (i.e. removal of the lipids from the stratum corneum), destroy its integrity. This destruction of the stratum corneum bilayers can lead to dry rough skin and may eventually permit the surfactant to interact with the viable epidermis, creating irritation.

Ideal cosmetic cleansers should cleanse the skin or hair gently, causing little or no irritation without defatting and or drying the skin and without leaving skin taut after frequent use. Most lathering soaps, liquids and bars fail in this respect.

Certain synthetic surfactants are known to be mild. However, a major drawback of most mild synthetic surfactant systems, when formulated for skin cleansing, is poor lather performance compared to the highest bar soap standards (bars which are rich in coconut soap and superfatted). On the other hand, the use of known high sudsing anionic surfactants with lather boosters can yield acceptable lather volume and quality. Unfortunately, however, the highest sudsing anionic surfactants are, in fact, poor in clinical skin mildness. Surfactants that are among the mildest, such as sodium lauryl glyceryl ether sulfonate, (AGS), are marginal in lather. These two facts make the balancing of the surfactant selection and the lather and skin feel benefit a delicate process.

Rather stringent requirements for cosmetic cleansers limit the choice of surface-active agents, and final formulations represent some degree of compromise. Mildness is often obtained at the expense of effective cleansing, or lathering may be sacrificed for either mildness, product stability, or both.

Thus a need exists for foaming cosmetic compositions which will produce a foam which is abundant, stable and of high quality (compactness), which are effective skin and hair cleansers and which are very mild to the skin, hair and occular mucosae.

It has been found that the use of specific polyol alkoxy esters in combination with specific amphoteric surfactants provide cosmetic cleansing compositions with significantly improved dermal mildness benefits and also good physical characteristics such as foaming.

It is therefore an object of the present invention to provide an improved cosmetic cleansing composition which thoroughly cleanses the skin and hair and which is very mild to the skin, hair and occular mucosae.

It is a further object of the present invention to provide an improved cosmetic cleansing composition which is mild and which will produce a foam which is abundant, stable and of high quality, and which effectively cleans skin and hair.

SUMMARY OF THE INVENTION

The present invention relates to foaming cosmetic compositions suitable for cleansing the skin or hair and which may be used as make-up removers and facial cleansers, bath foams, shower products, shampoos, and the like comprising:

(a) from about 0.1% to about 7.0% by weight on a solids basis of a first amphoteric surfactant of formula I selected from imidazolinium derivatives: ##STR1## wherein R₁ is C₈ -C₂₂ alkyl or alkenyl, R₂ is hydrogen or CH₂ COOM, Z is H, CH₂ COOM, CH₂ CH₂ COOM, or CH₂ CHOHCH₂ SO₃ M, Y is H, CH₂ COOM, CH₂ CH₂ COOM, or CH₂ CHOHCH₂ SO₃ M and M is H, alkali metal, alkaline earth metal, ammonium or alkanolammonium;

(b) from about 0.1% to about 5.0% of a polyol alkoxy ester; and

(c) from about 60% to about 99.5% water; wherein the ratio of (a):(b) is from about 15:1 to about 1:3 and wherein the cleansing composition has a viscosity of at least about 150 cps (Brookfield RVT, Spindle No TB, 10 rpm, 25° C.).

All concentrations and ratios herein are by weight of total composition and all measurements are at 250° C., unless otherwise specified.

DETAILED DESCRIPTION OF THE INVENTION

The invention relates to a foaming cosmetic composition with superior mildness and excellent lathering characteristics (abundance, quality) and good cleansing ability. The foaming cosmetic composition take the form of a viscous liquid, paste or gel which has the advantage that it can be easily and commercially packaged in and dispensed from pump bottles or from tubes by squeezing. Gel form compositions are defined herein as those which have a viscosity (Brookfield RVT, Spindle No. TB, 10 rpm, 25° C.) of at least 10,000 cps. Preferred from the viewpoint of flowability are gel compositions having a viscosity in the range from about 10,000 to about 50,000 cps, more preferably from about 10,000 to about 20,000 cps. Viscous liquids or pastes are defined herein as those having a viscosity (same conditions) of at least about 150 cps, preferably at least about 500 cps and less than about 10,000 cps, and more preferably between about 5,000 cps and about 9,000 cps.

Surfactant

The essential surfactant component of the compositions of the present invention is an amphoteric surfactant selected from imidazolinium surfactants of formula I ##STR2## wherein R₁ is C₈ -C₂₂ alkyl or alkenyl, R₂ is hydrogen or CH₂ COOM, Z is H, CH₂ COOM, CH₂ CH₂ COOM, or CH₂ CHOHCH₂ SO₃ M, Y is H, CH₂ COOM, CH₂ CH₂ COOM, or CH₂ CHOHCH₂ SO₃ M and M is H, alkali metal, alkaline earth metal, ammonium or alkanolammonium;

These amphoteric surfactants are present in the compositions of the present invention at a level of from about 0.1% to about 7%, preferably from about 0.1%, to about 5%, more preferably from about 0.1% to about 3% and most preferably from about 0.1% to about 2.5%, on a solids basis.

Examples of suitable amphoteric surfactants for use herein include compounds in which R₁ is C₈ H₁₇ (especially iso-capryl), C₈ H₁₉, C₁₁ H₂₃ and C₁₂ H₂₅ alkyl. Especially preferred are the compounds in which R₁ is C₁₂ H₂₅, Z is CH₂ CO₂ M, Y is CH₂ COOM and R₂ is H. These surfactants are all fully described in Miranol Products for Cosmetics and Toiletries Technical and Product Development, Tenth Edition (1987); which is incorporated by reference herein.

It will be understood that a number of commercially-available amphoteric surfactants of this type are manufactured and sold in the form of complexes with anionic surfactants, especially those of the sulfated C₈ -C₁₈ alcohol or C₈ -C₁₈ acyl glyceride types. More preferably, the compositions comprise the surfactant component along with a premix or complex of the optional amphoteric surfactant and anionic surfactant in an equivalent ratio of about 1:1 in order to provide approximate electroneutrality.

In a preferred embodiment of the present invention, the compositions comprise a second amphoteric surfactant being selected from aminoalkanoates of formula II

    R.sub.1 NH(CH.sub.2).sub.n CO.sub.2 M                      II

iminodialkanoates of formula III

    R.sub.1 N[(CH.sub.2).sub.m CO.sub.2 M].sub.2               III

and mixtures thereof, wherein n and m are numbers from 1 to 4, and R₁ and M are independently selected from the groups specified in I above.

The compositions herein can also comprise other optional surfactant components, notably, anionic surfactants. It is an important feature of the invention, however, that the combined concentration of the first and the optional second amphoteric surfactants is at least about 30% by weight of the total surfactant concentration, this being important from the viewpoint of achieving optimum lathering characteristics. In preferred compositions, the mixture of the first and second amphoteric surfactants comprises at least about 60%, more preferably at least about 75% by weight of the total surfactant composition.

Examples of suitable optional amphoteric surfactants for use herein include salts, especially the triethanolammonium salts and salts of N-lauryl-beta-aminopropionic acid and N-laurylimino-dipropionic acid.

The compositions herein preferably contain from about 1% to about 10% by weight, more preferably from about 1.5% to about 5% by weight of each of the first and second amphoteric surfactants. The weight ratio of first amphoteric surfactant:second amphoteric surfactant is preferably from about 10:1 to about 1:10, more preferably from about 5:1 to about 1:5, and especially from about 3:1 to about 1:3.

A preferred optional surfactant in the compositions herein is an anionic surfactant. This is preferably present in a level of from about 0.1% to about 10%, more preferably from about 1.0% to about 8%, and especially from about 4% to about 6% by weight.
